Remediation mechanism of EK-PRB coupling remediation of Cd-contaminated soil

open access: yesMeitan xuebao
Electrokinetic permeable reaction barrier (EK-PRB) coupled remediation technology combines the advantages of both electrokinetic remediation and permeable reaction barrier, which can effectively remove heavy metal ions from contaminated soil in coal mine

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

In-situ technologies for groundwater treatment: the case of arsenic [PDF]

open access: yes, 2014
Conventional technologies for treating contaminated groundwater such as pump-and-treat systems have several disadvantages due to its high cost, especially when the operation is long lasting and it becomes impossible to decrease the concentration below ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

open access: yesAdvanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Mechanics and Permeability Evolution Mechanism of Bedded Sandy Mudstone under Fluid-Solid Coupling Action

open access: yesTaiyuan Ligong Daxue xuebao
[Purposes] In order to better understand the permeability changes of coal measure bedded sandy mudstone under stress, the mechanical characteristics and permeability of bedded sandy mudstone were studied by discrete element simulation on the basis of the

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Isothermal Gasification of in Situ/ex Situ Coal Char with CO2 in a Micro Fluidized Bed Reaction Analyzer [PDF]

open access: yes, 2015
The so-called micro fluidized bed reaction analyzer (MFBRA) was adopted to implement the isothermal gasification of in situ coal char with CO2 under minimized external diffusion inhibition. It was done by keeping the reaction atmosphere and temperature

Grouting and re-bearing behaviors of sandy mudstone in the residual stage

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Grouting is an essential technique for reinforcing tunnel rock masses following deformation and failure. However, the mechanisms and effectiveness evaluation of grouting in fractured rock masses that have experienced substantial deformation and ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
